Nuffield Orthopaedic Centre NHS Trust and Oxfordshire Primary Care Trusts Shared Care Protocol and Information for GPs Sub-cutaneous methotrexate This leaflet provides the necessary information and guidance for the shared care of adult patients requiring subcutaneous methotrexate therapy and should be read in conjunction with the shared care agreement between Oxfordshire and Berkshire Primary Care Trusts and the Rheumatology Department. Introduction Methotrexate is recognised as the most effective of the traditional (non–biologic) disease modifying antirheumatic drugs ( DMARD’s) in current use for rheumatoid arthritis and related conditions. The optimum therapeutic dose of methotrexate should be achieved to minimise disease progression and joint erosions. Parenteral methotrexate can: Ensure the maximum bioavailability Reduce symptomatic side effects for some patients, thus increases in the therapeutic dose are better tolerated Extend the time that disease is controlled before expensive anti-TNF therapies need to be introduced. BSR guidelines (2003) state that whenever possible patients should have received methotrexate at a target dose of at least 20mg per week before anti- TNF treatment is considered. Improve the patients quality of life and satisfaction with treatment Dose and administration It is usually self administered in a range of 10-25 mg per week. Folic Acid supplementation is recommended at a dose of 5mg p.o per week, to be given 3-4 days after the methotrexate is prescribed. Supply - Methotrexate is supplied in named pre-filled syringes. APCO recommend supply of prefilled syringes of 50 mg/ml as Metoject© (Licensed). As agreed by APCO only Metoject® subcutaneous methotrexate preparations should be used within Oxfordshire. All prescribing of methotrexate subcutaneous should be via brand name. Disposal of Sharps. Cytotoxic sharps boxes need to be supplied. The initial cytotoxic pharmaceutical waste (sharps) disposal box will be provided by the Clinical Nurse Specialist in Rheumatology at initiation of treatment, when teaching the patient. Once full this should be returned sealed (for exchanging with an empty replacement white rose environmental cytotoxic pharmaceutical waste disposal box) preferably to the patients GP practice or in exceptional prearranged circumstances and only as part of a planned follow up clinical appointment to the rheumatology out patient department. Patients are advised to return their boxes for disposal and replacement when full or approximately every 3-6 months. Adverse effects. As for oral Methotrexate Please note that in addition to absolute values for heamatological indices a rapid fall or a consistent downward trend in any value should prompt caution and extra vigilance.

Anti emetic can be prescribed May respond to an increase in Folic Acid, 5mg, 3 days a week, which can be increased to 5mg, 6 days a week if necessary (omitted on day Methotrexate is taken) With hold until discussed with rheumatologist. Look for alternative causes. Re-challenge with lower dose once symptoms settle. Perform a differential and increase frequency of monitoring Neutrophils <2 X10^9/l Withhold, repeat WBC, if normal continue, otherwise discuss with rheumatologist Withhold until discussed with rheumatologist Platelets <150 X10^9/l Withhold until discussed with rheumatologist Liver function. >2 fold rise in ALT from upper limit of reference range Withhold until discussed with rheumatologist. Transaminase increase 2 X normal is common within 2 days of drug administration. Consider rechecking ALT at trough level. (i.e 0-2 days prior to injection) Reduce dose by 50% Increase frequency of monitoring Renal Impairment. i.e <30 mls minute eGFR MCV > 105 fl Unexplained fall in Albumin New or increased dyspnoea, or dry cough Significant reduction in renal function Alopecia Menstural dysfunction / Amenorrhoea Check folate. GGT, TSH B12. If B12 or folate low, start appropriate supplementation. Withhold until discussed with rheumatologist ? Pneumonitis particularly if accompanied by fever or night sweats. Withhold and refer to rheumatologist urgently ? alternative causes, reduce dose following discussion with rheumatologist.. Increase in hairfall is common, baldness is rare. May occur during treatment and for a short time following cessation. Notes: One weekly dose of Methotrexate can be withheld without inducing a flare. Methotrexate should not be stopped prior to elective surgery. Pneumovax and annual flu vaccinations are recommended. Contra Indications and Precautions Problem Pregnancy and breastfeeding Vaccination with live vaccines Chronic diver disease / Alcoholism Risk For men and women, contraceptive advice should be given, as pregnancy should be prevented for a minimum of 4 months after discontinuation of treatment. Breast feeding should be avoided. Severe antigenic reaction. Possible reduced immunological response to inactivated vaccines Alcohol can cause potential liver damage Written by M Cox / Verified by P Bowness. Version 8. (May 2011) Approved by APCO.

Withhold Methotrexate. Recent exposure (patients who have not had chickenpox) inform rheumatologist. Shingles – Active skin lesions, with hold Methotrexate and inform rheumatologist. Treat infection as appropriate give methotrexate unless symptoms significant. Drug interactions (refer also to BNF or SPC) NSAID’s in addition to the recommended doses of Methotrexate are not contraindicated. Concomitant use of other drugs with anti-folate activities i.e. Cotrimoxazole and Trimethoprim should be avoided. Monitoring Pre treatment assessment by Rheumatologist FBC, ESR, CRP, LFT’s and U&E’s will be checked prior to commencement. A baseline chest X-Ray. Lung Function tests may be requested in patients with risk factors or pre-existing lung conditions. Monitoring by GP FBC, ESR, CRP and LFT’s, U& E’s every two weeks for three months, then monthly. If possible blood tests should be taken at the trough level, i.e. on the morning before taking the Methotrexate. If the patient’s condition is stable the frequency of monitoring may be extended to 6 weekly at 6 months Blood results should be recorded in the shared care card. If a second DMARD is introduced as a combination, then the frequency of monitoring should be increased to the initial starting levels. Patient information leaflet Patients should be supplied with an information leaflet from the manufacturer. Shared Care Responsibilities Shared care assumes communication between the specialist, GP and patient. The intention to share care should be explained to the patient and accepted by them. Patients should be under regular follow-up which provides an opportunity to discuss drug therapy. a) Rheumatology Consultant Pre treatment assessment and recommendation of the appropriate DMARD to be prescribed. Write to the GP requesting shared care and outline shared care protocol criteria. Pre treatment counselling to include rationale for treatment, benefits, potential side effects, precautions and monitoring requirements ensuring patients understand their role in reporting adverse effects promptly. Teaching package provided by rheumatology Clinical Nurse Specialist re self administration of methotrexate. Issue written patient drug information, shared care monitoring booklet, contact telephone number. Ensure clinical supervision of the patient is done by follow-up as appropriate. Liaise with GP regarding changes in disease management, drug dose, missed clinic appointments. Provide telephone / email support in the event of any serious adverse reactions by a member of the medical team.
